An image scanning apparatus for making picture signals has an optical system for forming an image of an object on a predetermined plane and means for scanning the object image by a light-receiving surface disposed on the predetermined plane and generating an output indicative of the light intensity distribution of the object image on the plane. The apparatus comprising first driving means for moving the scanning means relative to the object image, second driving means for moving the scanning means relative to the object image in response to the completion of movement of the scanning means by the first driving means, means for controlling the exposure of the light-receiving surface of the scanning means during the movement of the scanning means by the second driving means in accordance with the output of the scanning means generated during the movement thereof by the first driving means; and means for processing the output of the scanning means generated during the movement thereof by the second driving means into a picture signal corresponding to the object image in accordance with the output of the scanning means generated during the movement thereof by the first driving means.
